Apple TV might work on one TV but not another due to several factors. Firstly, compatibility issues—ensure the TV's HDMI port supports HDCP (High-bandwidth Digital Content Protection). Second, resolution settings on Apple TV might not match your TV's capabilities; try adjusting these settings. Third, software updates can play a role; ensure both the Apple TV device and your TV firmware are up to date. Lastly, a faulty HDMI cable or port could be the culprit; trying a different cable or port might solve the issue.
